Unauthorized access on microfeed workflow error

I'm trying to create a workflow for a newsfeed and I'm having issues getting it to start.

Workflow steps is to log message to history list, send email, and log sent message. I've used the same steps testing a regular list and the workflows complete without issue.

The workflow gets stuck in 'Started' status. The error it gives is

Details of last request: HTTP Unauthorized to http://site/_vti_bin/client.svc/web/lists/getbyid(guid'GUID')

If i copy/paste this into the browser I can see the info just fine.

After a time it gets set to suspended status

HTTP 401 {"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access denied. You do not have permission to perform this action or access this resource."

I've tried setting permissions on the list, but have not had any successful results.
